Invasion of papaya mealy bug, Paracoccus marginatus in Assam.
This paper summarizes the results of a preliminary survey conducted in Dibrugarh district of Assam, India, to determine the status of pawpaw mealy bug (PMB), P. marginatus, invasion. The pawpaw plants have been attacked by the PMB for the first time in Dibrugarh. The first infestation of PMB was noticed during winter 2012. The infestation started increasing with the onset of dry spell durng the winter months and some plants, more particularly the plants which were attacked during March-April, could recovered from damage even after complete defoliation on receiving the pre-monsoon shower. Till date, the pest is restricted to urban/peri-urban area only. Birds such as crow, maynah and bat played a vital role in disseminating the pest from infested plant with ripe fruits to healthy one.
